摘　　要：介绍了气动位置控制系统ＰＣＭ控制方式的原理，设计了一种实现这种位置控制的实验系统。针对气动系统刚度低、阻尼小、易振荡的特点，实验中引入压力反馈补偿，提高系统的稳定性和动态性能，给出了实验装置、实验结果和分析。实验表明系统动态性能较好，位置控制重复精度达到±０．２ｍｍ，可用于对精度要求不高的实际场合。We have introduced the principle of the pneumatic position control system using PCM and designed a set of experimental device to accomplish this kind of control.Because of the disadvantages of pneumatic system such as weak stiffness and little damping ratio,pressure feedback is introduced into controllor in experiment to increase damping ratio and improve static and dynamic performance of the system.The experimental device,experimental results and the analysis are presented.The results show that the system has good performance and the repeat accuracy is up to ±0.2mm.
